rivt is an extensible, open-source Python tool for writing engineering calculation documents with a focus on reuse [1]. Python knowledge is not required but rivt capabilities can be extended with Python scripts that access scientific and engineering libraries.
There are four types of rivt document files:
| A rivt file is the basic input file that
rivt file | compiles to a text, PDF or HTML document.
| It is a Python file (.py) that imports the
| rivtlib Python package.
| A rivtbook is a collection of rivt files with
rivtbook | common subject matter and a folder structure
| that makes it easy to select files with related
| resources for inclusion in docs and reports.
| A rivt doc is the published output of a
rivt doc | rivt file. A doc (or chapter) is an output file
rivt chapter | formatted as text, PDF or HTML. Each format is
| compiled from the same rivt file.
| A rivt report is the published output
| of multiple docs collated into a single
rivt report | text, PDF or HTML file. Each doc is a
| chapter in a report. Chapters are
| grouped into divisions.
Examples of a rivt file with its text, PDF, and HTML docs are provided in a tutorial

The rivtlib Python package formats and compiles a rivt file to a text, PDF or HTML document (doc) in about a second. rivt file sections may be interactively executed in an IDE. Multiple rivt files may be compiled into a collated rivt report. rivt files may be organized into rivtbooks, collections around a common subject matter and organized for efficient selection and inclusion in reports. This website is an example of an HTML rivt report.
A convenient interface for searching and downloading public rivt files on GitHub is here. Open source engineering models, documents and examples, including rivt, may be downloaded from Google Drive.
rivt produces clear, organized engineering documents from active calculations using reasonable defaults. Use cases are listed here. Document tools like Quarto are likely better tools for static documents including journal articles and books that do not need recalculation. A brief discussion of current engineering document tools and their strengths relative to the objectives of rivt is here.
